Evidence of product effectiveness is a critical part of deciding whether to purchase products and services from educational publishers and educational technology providers. Students deserve to receive an evidence-based education--one in which instructional products and services and other educational practices are proven effective. School buyers demand proof of effectiveness and ESSA requires that sound effectiveness research be conducted before using ESSA funds for purchasing products and services. SEG Measurement has been conducting effectiveness research on behalf of educational publishers and. educational technology providers for nearly two decades. Schools can use this research to make better purchasing decisions. Publishers and technology providers can use effectiveness research to improve marketing and sales. Conducting quality effectiveness research is no longer an option for educational publishers and technology providers. Effectiveness research that meets the standards of the professional research community is a requirement.
